Abstract Adopting the principle of positive pressure method, a flow fluctuation durability test device has been designed through the customization and integration of air compressor, pressure regulator tank, pressure reducing valve and other basic parts. Its valve response time is less than 100ms, pipeline gas flow rate is not more than 5m/s, and the capacity pressure drop of the air source is less than 300Pa. The technical indexes meet the technical requirements of 2000h flow fluctuation mechanical durability test in the national recommended standard GB/T 6968-2019 Membrane Gas Meter.
